The carefully selected grades of high quality synthetic diamond are distributed in the depth of impregnated bit's matrix series. The matrix layer of the crown contains a uniform distribution of these crystals that are embedded in a powdered metal bond. The matrix of our impregnated bits is designed to expose new diamonds to the bits' cutting face as wear occurs. Fast penetration rate is maintained as a result of this action.The matrix layer of the impregnated diamond core drill bits crown contains a uniform distribution of these crystal diamonds that are embedded in a powdered metal bond. The main technical parameters of impregnated diamond core drill bits are diamond specifications, like type, size, concentration and grade, as well as matrix hardness type and crown shapes, which are selected according to the hardness and abrasiveness of the formation to be drilled. If user can make rational selections according to the rock formations, then they can get satisfied drilling performance on various formations with different hardness.Features:1: The impregnated diamond core bits features drilling speed and long service life2: The design of more cutting edges makes drilling progress smoother3: During the manufacturing process, the diamond is free erosion and fully utilized4: The impregnated diamond core drill bits are of various configurations and meet various needs of local conditions5: It offers the most widely-used bit matrices as well6: With various specifications, our series matrix range provide an easy selection and reliable foundation for your drilling needsSize: Our bits are available in all standard drilling sizes. Also, non-standard sized bits can be produced according to requirements from clientsMatrix height: 6mm-8mm (most cost-effective), 8mm-10mm (long service life), 12mm-16mm (super service life)Bit Crown Profiles: "W" profile, "Flat" profile, "Semi-round" profile, "Cross" profile, "Gear profile"Waterways: Various waterways are available for diamond impregnated bits. Differing waterways allow for better flushing in various ground conditions and drilling systems.Threads: Standard Q threads as well as thread types required by clients are availableIf you need any further information, please feel free to contact with us, we will be quite pleased to show all the details you asked for.Size:Wireline Impregnated Diamond Core Drill BitSizeOutside diameterInside diameterinchmminchmmAQ1.880/1.87047.75/47.501.607/1.05727.10/26.85BQ2.350/2.34059.69/59.441.438/1.42836.52/36.27BQ32.350/2.34059.69/59.441.325/1.31533.65/33.40NQ2.970/2.96075.44/75.191.880/1.87047.75/47.50NQ22.970/2.96075.44/75.192.000/1.99050.80/50.55NQ3, NWLTT2.970/2.96075.44/75.191.780/1.77045.21/44.96HQ3.770/3.75595.76/95.382.505/2.49563.63/63.38HQ3, WLHTT3.770/3.75595.76/95.382.411/2.40161.24/60.99PQ4.815/4.795122.30/121.803.350/3.34085.09/84.84PQ34.815/4.795122.30/121.803.275/3.26583.18/82.93Related Pictures:Production Flow:Packaging & Shipping:Using plywood case package for sea shipment, and using carton packages for air delivery.Contact Us:
